Appli ation filed March 19,1398. Serial No. 674,425. (No model.)

T0 at whom it may concern.-

Be it known that I, JOHN XV. SCHELL, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Automatic Disinfectors,which improvement is fully set forth in the following specification andaccompanying drawings.

My invention consists in an improved construction of automaticdisinfector which is especially adapted for use in connection withwater-closets, urinals, tanks, the, provision being made for enablingthe disinfector to be come operative only when the closet is flushed andmeans being also provided for measuring the disinfectant, if desired,whereby onlya certain predetermined quantity thereof will be directedinto the water-closet or bowl.

It further consists of novel features and details of construction, allas will be hereinafter fully set forth, and particularly pointed out inthe claims.

Figure 1 represents a vertical sectional view of an automaticdisinfector embodying my invention, certain of the parts being shown inelevation. Fig. 2 represents, on an enlarged scale, a section on line 00:0, Fig. 1. Fig. 3 rep- .resents a similar view to Fig. l, but showing asomewhat modified form thereof. Fig. 4 represents, on an enlarged scale,a sectional view of a valveemployed.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, 'A designates an automatic disinfect-or, thesame consisting of the usual flushing-tank B, which has a pipe orconduit G leading therefrom to any desired pointsuch, for instance, as awater-closet or urinal. The flow of water from said tank through thepipe 0 is controlled in any suitable manner or with the ordinary floatDand other necessary or desired mechanism; but as the'saine forms no partof the present invention a detailed description thereof is not heredeemed necessary.

E designates a reservoir which may be located at any desired-point withrelation to the closet bowl or other objective point, where it isrigidly secured against displacement in any convenient manner,saidreservoir being charged with the disinfectant fluid F and thedischarge of the latter being controlled by means to be hereinafterreferred to.

G designates a valve-rod which is shown in Fig. 2 as having at its lowerend a valve H, adapted in its normal position to remain upon a seat M ofa shell or casing N, within which casing is formed a chamber P toreceive the disinfectant from the reservoir E. \Vhen the reservoir E islocated at a distance from or below the tank B, the disinfectant isallowed to flow from the valve-casing N through a suitable pipe whichleads fromsaid casing to the bowl of the closet or other objectivepoint, when the valve or valves are moved by mechanism hereinafterdescribed. In Fig. 3 the valve-rod G has a single valve G attachedthereto, said valve controlling the port Gr in the casing G.

The upper end of'the rod G is pivotallysecured to a lever B, which isfulcrnmed to a bracket S, the other end of said lever being pivotallyattached to a rod or sleeve T, which passes through a guide W, its lowerend being connected in Fig. 3 to the'inverted cup or receptacle O whichis provided with a flapvalve C normally covering an aperture 0 throughwhich the air accumulating above the water and between the inner upperportion of the cup or receptacle O may be allowed to escape as the waterfills the tank B and passes into said cup or receptacle.

A spring B is placed upon the sleeve '1, one end of which is secured tothe guide TV, while its opposite extremity is fastened to a collar A,secured to the sleeve T, the function of said spring being to raise thecup or receptacle 0 after the water has flowed therefrom or at otherdesired periods.

One end-of a chain W is secured to the valve 0 and the other end isfastened to a suitable point, as the guide Y, through which the rod Xpasses, which latter engages the cup (J and is secured in the sleeve Tby means of the collar and set-screw Z, said chain being adapted to openthe valve 0 at the proper interval in order that the water containedtherein may flow therefrom as it leaves the tank, it being apparent thatwhen the chain becomes taut and the cup or receptacle continues in itsdescent the valve 0 will be raised to allow the air to enter, inconsequence of which said cup will empty at the l desired moment andrise through the action of the spring B referred to, thus closing thevalved outlet leading from the disinfectantreservoir and stopping thedischarge of the fluid.

hen the mechanism is operated to flush the closet, the water as it flowsout of the tank B will create a suction within the cup or receptacle,and until this suction is broken it will continue to descend, thusraising the valve H from its seat and permitting discharge of thedisinfectant until such time as the chain \V, as above described, opensthe valve C and allows the air to enter, when the water will quicklyflow from the receptacle and the downward movement thereof will cease,the spring B serving to raise the cup or receptacle to its normalposition.

In Figs. 1 and 2 I employ two valves instead of the one referred to withrelation to Figs. 3 and 4, the construction of which valves has alreadybeen described. The valve H (seen in Fig. 2) remains normally seated,while the valve K remains unseated until such time or times as themechanism is manipulated to flush the water-closet-, at which time thevalve H will be unseated and the valve K seated, thus allowing the fluidwhich has been contained in the chamber P to flow into the tank,commingle with the water therein, and thus disinfect the closet.

The cup or receptacle 0 is arranged in Fig. 1 in reverse position tothat described with relation toFig. 3, and the lower end of the rod X issecured thereto, while the upper end of said rod passes through aguide Yand thence into the sleeve T, wherein it is held by means of a set-screwZ. The upperend of the sleeve T passes through a guide \V, as alreadydescribed,and a collar Uis arranged upon said sleeve and is adjustablethereon in both cases through the medium of the set-screw V, so as tolimit the downward movement of the cup or receptacle 0.

The spring B" is arranged, as already described, so that it can bereadily adjusted, and consequently afford a greater or less resistanceto the downward movement of the cup in order that the output ofdisinfectant fluid may be properly regulated.

The flap-valve C is dispensed with, and the cup 0 is provided with aseries of perforations D', said cup becoming full of water as the tank Bitself becomes filled,eitherthrough said perforations or over the sidesof the cup, so that when the mechanism is operated to flush the closetthe water will first leave said tank B and then flow through theperforations D, after which the spring B will force the sleeve Tupwardlyin the direction of the arrow seen inFig. 1, thus causing thevalverod G to descend to seat the valve H and unseat the valve K, and sopermit the discharge of the disinfectant fluid into the tank B, as abovedescribed, said tank being now substantially empty.

The perforations D referred to are of such character as to permit thewater in the cup or receptacle 0 to empty more or less slowly to suitvarying requirements and to enable the spring B to act to move thesleeve T upwardly more or less quickly, so that the valves H and K maybe moved to cut off the flow of the disinfectant fluid at anypredetermined time in order that unnecessary waste thereof may beavoided.

In the practical application of my invention the tank E is located sothat the outlet in the casing N willbe directly in alinement with thepipe 0, although this is not absolutely essential, and instead ofdischarging the disinfectant fluid directly into the bowl of the closetor into the tank B itself I may employ a pipe (not shown) which willconnect with the discharge end of the chamber P and lead directly intothe pipe or conduit 0 or other desired point.

To regulate the amount of disinfectant to be discharged from thereservoir with relation to the amount of water used at each flushing ofthe closet, as constructed according to Fig. 3 of the drawings, it isonly necessary to shorten the chain \V, so that more or less movementmay be given to the cup or receptacle, it being apparent that byshortening the chain the sooner the water will leave the cup orreceptacle and allow the spring B to close the valve, as beforedescribed, and vice versa. The desired regulation is effected byadjusting the rod X within the sleeve T so that the cup employed willrest at any predetermined or desired elevation, as the Weight of thewater in the cup or receptacle will begin to lessen when the closet isbeing flushed and so remove the resistance to the spring more quickly,thus opening the valves and keeping them open until the tension of thespring overbalances the water in the cup and brings the cup orreceptacle back again to its normal position.

The collar U is adjustably mounted upon the rod or sleeve T and isintended to limit the downward movement of said rod or sleeve, so thatthe valve H (shown in Fig. 2) by its intermediate connections maybecaused to rise to a greater or less extent to permit any requiredquantity of disinfectant to flow from the chamber P. The collar U may ofcourse be entirely dispensed with and the fiowof the disinfectant beregulated in the manner hereinbefore described; but I have deemed itadvisable to use said collar, as it; is evident its abutment against theguide W in the descent of the rod or sleeve will serve to remove allstrain upon the valves and prevent them from leaving their seats throughthe resiliency of the spring B.

It will be evident that, if desired, I may employ a plurality of valvedoutlets from the tank E, according to requirements.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
